java版世界时钟示例

这是一个java版的世界时钟示例，移植自gerrit创建的同名swing应用（http://www.jug-muenster.de/swing-worldclock-427 ），需要运行在jre1.5或以上环境当中。

 

移植此示例主要是因为前一阵移植过gerrit的swing原子钟示例，所谓好事成双，这个世界时钟的示例自然不能放过（话说gerrit为什么那么喜欢做时钟？……），毕竟java桌面应用实例本就不多，但凡有参考价值的还是要多做汇总才好。

 

另外，此示例中关于多时区的分辨与显示部分，在非桌面应用中也具备一定的参考价值。

 

ps:由于此示例以lgame-simple-0.2.5开发，所以也可以看作是世界时钟的awt实现。

运行代码如下所示（构建过程省略了swing原版的一些步骤）：
